简介
Objectives
In the present study we retrospectively analyzed ventriculographic data from symptomatic patients after myocardial infarction who underwent the Dor procedure (endoventricular circular patch plasty repair) to evaluate left ventricular shape 1 year after the operation and to analyze the geometric correlates of late mitral regurgitation.
Methods
Forty-four patients with previous transmural anterior myocardial infarction comprised the study group. Left ventricular volumes, global left ventricular systolic and diastolic sphericity, the extent of wall motion abnormalities, and the presence and degree of mitral regurgitation were analyzed before and 1 year after operation.
Results
Comparing preoperative diastole to systole within the cardiac cycle, left ventricular shape becomes more elliptical in systole than it was in diastole (eccentricity index closer to 1). The intervention leads to an increased diastolic sphericity, but for …
